<p>DUAL BELT PULP WASHER A machine and process for washing paper stock pulp and similar free-filtering materials includes two or more horizontally-disposed wash drums (11) mounted each in a tank (45). Two endless filter belts (83 and 85) are trained to pass under each of said wash drums (11) and through liquid contained in each of the tanks (45). A mat of pulp (102) is formed between the two endless filter belts (83 and 85) and carried under each of the wash drums (11) for washing therein. Wash liquor passes through the pulp mat (102) as it travels under each of the drums (11) thereby washing the pulp mat, and the liquor passes between the drums (11) and the tanks (45 and 47) by gravity flow. After the pulp has been washed it is removed from between the two belts (83 and 85).</p> |
